hi joe .
In everything I have read on or about Cetswayo , he never said once he was going to invade Natal .
If he had done after Isandlwana who knows what the outcome would have been . So its fairly safe
to say in my opinion the answer is most certainly a no . A s he did think the british were on his side
so to speak , He did maintain that if he was invaded he would defend his lands .
cheers 90th.
